Glyphosate

Definition

Glyphosate was discovered in Switzerland in 1950.

Since then, it’s become one of the most widely-used broad-spectrum herbicides globally. It acts on annual and perennial weeds by blocking a key enzyme plants need to grow. Without this enzyme, the weed wilts to the ground 4-7 days after application.

Glyphosate is not absorbed by plant roots and microbes in the soil break down glyphosate into primarily naturally-occurring substances.
